If you're an avid hiker, or simply love the outdoors, the W Trek in Patagonia should be high on your travel bucket list. This multi-day hike takes you through some of the most stunning scenery in the world, including snow-capped mountains, beautiful lakes, and vast glaciers. The W Trek is an unforgettable journey through the heart of Torres del Paine National Park.

What is the W Trek in Patagonia?

The W Trek is one of the most iconic multi-day hikes in the world, winding through the stunning landscapes of Torres del Paine National Park in Chilean Patagonia. 

The route gets its name from the shape it forms on the map, resembling a 'W', as it snakes through three main valleys: Valle Ascencio, Valle del Francés, and Valle del Glaciar Grey. 

Covering around 70-80 kilometers (43-50 miles), the W Trek typically takes 4-5 days to complete. 

Along the way, you'll experience a mix of towering granite peaks, lakes, glaciers, and some of the most jaw-dropping scenery in South America.

How to get to Torres del Paine National Park?

The starting point for the W Trek is usually Puerto Natales, a small town about 2-3 hours away from the park. To reach Puerto Natales, most travellers fly into Punta Arenas Airport (PUQ) from Santiago, Chile. From there, buses run regularly to Puerto Natales.

Once in Puerto Natales, you'll need to take a bus to the Laguna Amarga entrance or Pudeto depending on your chosen starting point.

Accommodation options

On the W Trek, you can choose between:

• Camping (with or without gear rental)
• Refugios (mountain lodges)
• Full-board packages (meals + accommodation)

Bookings for both refugios and campsites need to be made months in advance, especially during peak season (November to March).

What to pack for the W Trek

You’ll want to be well prepared so the hike goes as smoothly as possible. So, don’t forget to bring…

• Sturdy hiking boots
• Waterproof jacket & pants
• Warm layers (Patagonia weather is unpredictable!)
• Sleeping bag (if camping)
• Lightweight tent (if not renting)
• Water bottle + filter or purification tablets
• Snacks & lightweight meals
• Trekking poles

💰 Don't forget to bring cash – there are no ATMs in the park!

Best time to hike the W Trek

The best time to hike the W Trek in Patagonia is during the summer months (November to March) when the weather is milder. However, be prepared for all four seasons in one day – wind, rain, sun, and even snow can all happen within a few hours.

Tips for hiking the W Trek

• Book in advance, as campsites and refugios sell out quickly.
• Try to only bring the essentials – every extra kilo will feel heavier after a few days, so pack light.
• Weather conditions tend to be better in the morning, so it’s good to do early starts.
• Respect the park rules. Pack out all trash and stick to marked trails.

Hiking the W Trek in Patagonia is a once-in-a-lifetime adventure. The landscapes of Torres del Paine National Park are unlike anywhere else in the world, hence being on so many people’s bucket list.
